Abstract: The invention relates to a method and a device for making lower leg prostheses, comprising a prosthesis sleeve, a prosthesis foot and a connecting member interconnecting said prosthesis sleeve and said prosthesis foot. In said method the desired position of said prosthesis foot in relation to said prosthesis sleeve is determined and a prosthesis sleeve is then formed on a prosthesis sleeve positive while simultaneously securing said connecting member to said prosthesis sleeve in the desired position.A support device for use in said method comprises first fastening means for a support for said prosthesis sleeve positive and second fastening means for mounting adapter means for said prosthesis foot, said first and second fastening means being adjustable in relation to each other to permit reproducible setting of said fastening means corresponding to a desired positioning of said prosthesis foot to said prosthesis sleeve.

Abstract: A guiding device for orthosis, comprising an anti-friction screw and nut assembly, in which the nut comprises two interconnected nut portions, which are rotatable but not axially displaceable relatively to each other, each nut portion having an axial bore for receiving said screw and at least two anti-friction bearings, each arranged to contact a thread groove of the anti-friction screw, said screw and one of said nut portions having means for attaching the same to an orthosis or to a support.
